WATER-WH EEL.

SPECIFICATION forming part of Letters Patent N 0. 576,849, datedFebruary 9, 1897..

Application filed December 5, 1896. Serial No. 614,553. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL HUG, a citizen of the United States, residingat Denver, in the county of Arapahoe, State of Colorado, have invented anew and useful Improvement in Water-Wheels, which improvement is fullyset forth in the following specification and accompanying drawings.

My invention relates to water-wheels and it consists more especially inan improved construction of bucket therefor, in which the lower wall isgiven a continuous curvature or are shape throughout substantially itsentire length, so as to facilitate the discharge of the water from theside chambers of the bucket, thereby reducing to a minimum allpossibility of foaming and at the same time cushioning the motive fluidand causing all the latter to be discharged in a solid stream at eitherside of the bucket.

It also consists of an improved construction of fastening device wherebybuckets of large dimensions can be expeditiously and rigidly attached tothe rim of the water-wheel.

It further consists of novel details of construction, all as will behereinafter fully set forth, and specifically pointed out in the claims.

Figure 1 represents a front elevation of a bucket embodying my inventionFig. 2 representsarear elevation of the bucket. Fig. 3 represents asection on line mm, Fig. 1. Fig. 4 represents a section on line y y,Fig. 1.

Fig. 5 represents a section on line as, Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates my improved construction ofbucket, the same having the lower front wall or edge B, from whichextends the rearwall O, to which latter is given a curvature or areshape, thereby imparting to the portion D, at or near which the incomingfluid first strikes, a continuous rounded surface, whereby allobstruction to the discharge of water from the bucket is prevented andfriction is reduced to a minimum.

E designates chambers, located side by side, which are formed betweenthe flaring side Walls F of the bucket and the convergingcentrally-located walls G, which meet to form the apex H, the latterbeing a short distance from the outer line of the bucket within thelatter, as will be evident from Figs. 3, at, and 5.

J designates a substantially centrally-located V-shaped wall, the sidesK of which assist to form the chambers L of the bucket, said chambersbeing locatedin the upper portion of the latter and forming acontinuation of the chambers E and having their sides flaring outwardly,as indicated in Fig. 1, the flaring outer walls M of the bucket beinglocated oppositely to the sides K, and thus giving to the chambers L thedesired contour, it being noted that the outlet L of each of saidchambers is slightly contracted and curved, so that the full effect ofthe impinging fluid is obtained.

N designates the top of the bucket, which in the present instance slopesfrom front to rear, as indicated in Figs. 3 and 5, the top surface ofthe bucket being continued to form the plate P, which is attached to thetop M substantially at an obtuse angle in the present instance, saidplate being adaptedto contact with the outer periphery of the rim Q ofthe water-wheel, as indicated in Fig. 5.

R designates openings in said plate for the insertion of a screw, bolt,or other suitable fastening device R.

S designates a strengthening-rib common to the rear curved wall 0 of thebucket and the plate P.

T designates a lug or tenon which projects from the top M of the bucket,the top of said tcnon in the present instance being inclined atsubstantially the same angle as the top N, although, of course, thisdegree of inclination can be varied, if desired. The front wall of saidtenon T is provided with a curvature V, whereby an overhang or lip 1V isproduced, the rear of said ,tenon having the inclined face X, it beingof course understood that the tenon Tis adapted to seat in asimilarly-shaped recess W in the rim Q of the water-wheel, as indicatedin Fig. 5.

The operation is as follows: The incoming fluid is received in the lowerportion of the chambers E and discharged at the points L from the upperchambers L, the general operation being substantially the same as thatdescribed in a contemporaneously pending application filed by me on the1st day of October, 1896', Serial No. 607,529, the special feature towhich it is desired to direct attention in the present instance beingthe contin uous uniform curvature given to that portion D of the wall Gupon which the actuating fluid first impinges. The bucket is secured inposition by inserting the tenon T in the proper recess, it being ofcourse understood that there are as many recesses in the rim of thewater-wheel as there are buckets to be carried thereby, the said tenonbeing first inserted in place and then moved forwardly until the lip Wis in contact with the adjacent surface, against which it is driven bythe inclined edge X of the tenon when the plate I? is forced in place inthe act of fastening, the plate P being then secured by means of thefastening device R to the rim of the wheel, it being thus apparent thatthe bucket after being secured in position is rigid in place and cannotbe moved sidewise, laterally, or in any other direction, the abovemanner of fastening being used on very large buckets in which the tenonwould be too wide to pass through the rim of the wheel withoutdangerously weakening the same.

It will of course be understood that slight changes may be made by thoseskilled in the art which will come within the scope of my invention, andI do not therefore desire to be restricted in every instance to theexact construction I have herein shown and described.

I disclaim a bucket having a plurality of diverging chambers and aV-shaped wall, the sides of which assist in forming the said chambers,which latter discharge at opposite sides of said bucket, as the sameforms the subject-matter of the claims of the pending application,hereinbefore referred to.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a water-wheel, a bucket having a plurality of diverging chambers,the upper portion of said bucket having a V-shaped wall therein, thesides of which wall assist in formin g said chambers, which latterdischarge at opposite sides of said bucket, and the walls of saidchambers upon which the incoming fluid first impinges being providedwith a curvature throughout their length.

2. In a water-wheel, a bucket having a plurality of diverging chambers,the upper portion of said bucket having a V-shaped wall therein, thesides of which wall assist in forming said chambers, which latterdischarge at opposite sides of said bucket, the rear wall of the lowerportion of said chambers being provided with a continuous curvature,whereby foaming is obviated, and the incoming fluid is cushioned, andmeans for attaching said bucket to a water-wheel.

3. In a water-wheel,a bucket having a tenon attached to the top thereof,said tenon being provided with a forwardly-projecting lip, and

said bucket having a rearwardly-projecting plate adapted to be attachedto the exterior periphery of the water-wheel.

4:. In a water-wheel, a bucket having a plurality of diverging chambers,the upper portion of said bucket having a V-shaped wall therein, thesides of which wall assist in forming said chambers, which latterdischarge at opposite sides of said bucket, and the top of the latterbeing inclined and provided with a tenon attached thereto, said tenonhaving an inclined top and rear wall, and a forwardlyprojecting lip incombination with a rearwardly extending plate, the latter being adaptedto be attached to the outer periphery of said water-wheel, and saidtenonbeing adapted to be seated in a recess in the rim of said wheel.

5. In a water-wheel, a bucket having a plurality of diverging chambers,the upper portion of said bucket having a V-shaped wall therein, thesides of which wall assist in forming said chambers, which latterdischarge at opposite sides of said bucket, the rear wall of each ofsaid chambers being provided with a continuous curvature at that pointupon which the actuating fluid first impinges, a tenon attached to thetop of said bucket, and provided with a forwardly-projecting lip, aplate projecting rearwardly from the upper portion of said bucket, and astrengtheningrib common to the latter and said plate.

(5. In a water-wheel, a bucket A having a plurality of chambers Etherein, the walls F, G, of said chambers diverging outwardly, and therear wall 0 of said chambers being provided with a continuous curvatureat about the point where the in coming stream first impacts therewith, aV-shaped wall J located in the upper portion of said bucket, thechambers L, the sides of said V-shaped wall assistin g in forming saidlatter chambers, the same being provided with curved and contractedoutlets, the tenon T attached to the top of said bucket and providedwith an inclined top, and having the rear walls U and X respectively,and the curved front wall V and the lip V, the rearwardl y-extendin gplate P attached to the upper portion of said bucket and extending at anobtuse angle to the top of the latter, the strengthening-ribs S commonto said plate and bucket and means for attaching the latter to awater-wheel.
